Amazon Linux AMI : net-snmp (ALAS-2021-1465)

medium Nessus Plugin ID 145001

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of net-snmp installed on the remote host is prior to 5.5-60.22. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1465 advisory.

 A flaw was found in Net-SNMP through version 5.73, where an Improper Privilege Management issue occurs due to SNMP WRITE access to the EXTEND MIB allows running arbitrary commands as root. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-15862)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update net-snmp' to update your system.
